Introduction

In mathematics, a scale model is a representation of a real-world object or space at a smaller size. Scale models are used in various fields, including architecture, engineering, and design. When creating a scale model, it's essential to maintain the same proportions as the original object or space. In this article, we'll explore how to determine the correct dimensions for a scale model of a room with a length of 22 feet and a width of 25 feet.

What is a Scale Model?

A scale model is a representation of an object or space at a smaller size, while maintaining the same proportions as the original. Scale models are used to visualize and understand complex designs, systems, or structures. They can be used to test and refine ideas, identify potential issues, and communicate designs to stakeholders.

Key Concepts in Scale Modeling

When creating a scale model, there are several key concepts to consider:

Scale ratio: The scale ratio is the relationship between the size of the model and the size of the original object or space. It's usually expressed as a fraction or a ratio of the model's size to the original size.
Proportion: Proportion refers to the relationship between the different parts of the model and the original object or space. It's essential to maintain the same proportions as the original to ensure that the model accurately represents the object or space.
Unit of measurement: The unit of measurement used for the model should be consistent with the unit of measurement used for the original object or space.

Determining the Correct Dimensions for a Scale Model

To determine the correct dimensions for a scale model of a room with a length of 22 feet and a width of 25 feet, we need to consider the scale ratio and proportion.

Let's assume we want to create a scale model with a length of 6.5 inches and a width of 7.5 inches. To determine if this is a valid scale model, we need to calculate the scale ratio and check if it maintains the same proportions as the original room.

Calculating the Scale Ratio

The scale ratio can be calculated by dividing the model's size by the original size. In this case, the scale ratio for the length would be:

6.5 inches (model) ÷ 22 feet (original) = 0.2955 (scale ratio)

The scale ratio for the width would be:

7.5 inches (model) ÷ 25 feet (original) = 0.3 (scale ratio)

Checking the Proportion

To check if the model maintains the same proportions as the original room, we need to compare the ratio of the length to the width in both the model and the original room.

In the original room, the ratio of the length to the width is:

22 feet (length) ÷ 25 feet (width) = 0.88

In the model, the ratio of the length to the width is:

6.5 inches (length) ÷ 7.5 inches (width) = 0.8667

As we can see, the ratio of the length to the width in the model is very close to the ratio in the original room. This suggests that the model maintains the same proportions as the original room.

Conclusion

In conclusion, to determine the correct dimensions for a scale model of a room with a length of 22 feet and a width of 25 feet, we need to consider the scale ratio and proportion. By calculating the scale ratio and checking the proportion, we can ensure that the model accurately represents the original room.

Answer

Based on the calculations above, the correct dimensions for a scale model of the room could be:

Length = 6.5 in.
Width = 7.5 in.

This is option A in the discussion category.

Additional Options

Let's also consider the other options:

Option B: Length = 17.6 in.; Width = 19.5 in.
Option C: Length = 11 in.; Width = 12.5 in.
Option D: Length = 13

We can calculate the scale ratio and check the proportion for each of these options to determine if they are valid scale models.

Calculating the Scale Ratio for Option B

The scale ratio for the length would be:

17.6 inches (model) ÷ 22 feet (original) = 0.8 (scale ratio)

The scale ratio for the width would be:

19.5 inches (model) ÷ 25 feet (original) = 0.78 (scale ratio)

Checking the Proportion for Option B

The ratio of the length to the width in the original room is:

22 feet (length) ÷ 25 feet (width) = 0.88

The ratio of the length to the width in the model is:

17.6 inches (length) ÷ 19.5 inches (width) = 0.901 (scale ratio)

As we can see, the ratio of the length to the width in the model is not the same as the ratio in the original room. This suggests that the model does not maintain the same proportions as the original room.

Calculating the Scale Ratio for Option C

The scale ratio for the length would be:

11 inches (model) ÷ 22 feet (original) = 0.5 (scale ratio)

The scale ratio for the width would be:

12.5 inches (model) ÷ 25 feet (original) = 0.5 (scale ratio)

Checking the Proportion for Option C

The ratio of the length to the width in the original room is:

22 feet (length) ÷ 25 feet (width) = 0.88

The ratio of the length to the width in the model is:

11 inches (length) ÷ 12.5 inches (width) = 0.88 (scale ratio)

As we can see, the ratio of the length to the width in the model is the same as the ratio in the original room. This suggests that the model maintains the same proportions as the original room.

Calculating the Scale Ratio for Option D

The scale ratio for the length would be:

13 inches (model) ÷ 22 feet (original) = 0.5909 (scale ratio)

The scale ratio for the width is not provided, so we cannot calculate the proportion for this option.

Conclusion

In conclusion, the correct dimensions for a scale model of a room with a length of 22 feet and a width of 25 feet could be:

Length = 6.5 in.
Width = 7.5 in.
